Module telemetry 

2026-09-26: The open-PR telemetry comment: which kernel targets each PR re-opens, which targets more than one open PR re-opens, a recommended merge order, and promotion-candidate debt.

render reads only its PrFacts and the tree (the kernel taxonomy and CODEOWNERS); the pr-telemetry workflow collects the facts from GitHub and posts the body. The comment is advisory: render returns only text.

Owner: bench gate. Invariants:

• A PR with paths_unknown is counted at the widest reach, every target and every promotion candidate, and render lists such PRs (through order::cap_prs) in a warning before the tables.
• The body always starts with MARKER_START and ends with MARKER_END and a newline.
